Well, I don't really want to sound overly pessimistic, and really, I have little data to back up my claims, but some common sense will pretty much answer that question for you.
Whatever you want to sell, you need to sell to your target audience. Now, generally on Crowd sourcing sites such as Kickstarter you are "selling" to your future audience... gamers that might want to play your future game. As such, even trying to explain to them what "programmer art" is is going to be a tough nut.
Now, there are different thresholds for what makes art "acceptable", "good" or "awesome" in players eyes. Not only is every person different, but also different genres bring different expectations with them, shaped both by the general needs of the genre and the titles that were released before. Then there are special niches that make "not so good" art more acceptable... retro style gaming, for example (and thats the main reason for the tide of "pixel style" graphics).
So no, programmer art will most probably not cut it anymore on Kickstarter. You might get away with it if you try to pitch your game prototype to a studio or publisher (if you had the expierience to back up the claims that you can build that game in the first place)... you will not get away with it if have to pitch to your potential customers, gamers.
On the plus side, just because some games are coming to Kickstarter with much better graphics than you do, doesn't mean you couldn't have success with your art style. Your games graphics have to suit your game first and foremost, and be accepted by your potential customers. Sometimes you can be surprised what graphics are still accepted by gamers, and even manage to be quite successfull with their "programmer like art" (See minecraft or thomas was alone).
Finding an artist ready to work on such a basis might prove challenging. You do bring a prototype with you, that will make things much easier (the artist can see you are serious about the project, and being able to get into a project with the technical side already in place means he can see his art moving as soon as he finishes it... both things are motivation boosts to the artist).
Maybe see if you can find somebody on deviantart ready to work with you? Or put up a classified here on gamedev to see if you can find a hobbyist that is looking to form a team. Generally there are more artists looking for a gig around than programmers, so its easier that way around.
